Answer 1

1) We knowt Energy E= Q^{​​​​​​2}​​​/2C or CV^{​​​​​2}/2

We know that C=

For constat Voltage the E is inversely proportional to d

For constat charge the Energy is directly proportional to the distance between plates d

2)We know V= Ed so as V increases E also increases so Electric Field changes directly

3) For constant voltage E is inversely proportional to the distance between plates

Since E is directly proportional to charge on plate we can say that charge is inversely proportional to distance between plates

4) E= for constant E i.e constant voltage the Q and A are inversely proportional to each other

5) E = so as A increases the Electric Field decreases so inversely changes

6) Energy = QV/2 for constant charge the Energy has a direct relationship with V

For constant C the Energy has direct relationship with V^{​​​​​​2}

7) C changes directly with A from formula said above

8) for increase in V the Electric Field increases for constant area increases in electric field increases the Charge so V and Q has a direct relationship

9) For increase in V and constant Q the V and C are in inverse relationship with each other.

Since Q=CV
